I was reinstalling my loader onto my B2620 today and could not get the red marked hydro line to connect, I took a phillips head screwdriver and poked the button inside the fitting to relieve pressure on the tractor side fitting and still couldn't get the line to connect. Then I tried to relieve pressure on the fitting on the loader line and couldn't press in the little button. So I took a 1/2in allen socket and put it against the button on the loader line and tapped it with a hammer and it shot hydro fluid out and then reconnecting the line was a breeze. Has anyone else out there encountered this and what was your solution?
